thaler linotype-machines of the form repre-.

sented in Letters Patent of the United States No. 615,909, wherein circulating matrices each containing two distinct characters are employed. These matrices have one character placed above the other. In assembling the matrices in line they are adjusted individually at a higher or lower level, according as one character or the other is to be brought into action, or, in other words, they .are so adjusted that the character to be used will stand at the alining or casting level.

The line is composed in the assembling-elevator and transferred laterally through a stationary intermediate channel to the first elevator, by which the line is lowered to a castinga position at the mold. The intermediate ch nnel, like the assembling-elevator, is pro- .vided with two horizontal guides or shoul ders lying one above the other to engage theears of the matrices and maintain them at theproper heigh The assembling-elevator is raised when the composition of the line is completed to the level ofthe intermediate channel, through which the matrices are to It sometimes happens that I the matrices arethrown upward from their lower osition in the elevator if the operator lifts t e same with excessive speed, and in such case the ears of the matrices will fail to pass properly into the lldlIl channels or grooves in the intermediate c annel. The object of my invention is to avoid this difficulty by insuring proper seating of the matrices in osition for their ears to ass through the gui es in the intermediate 0 annel. To this end I make use of a movable switch in any form adapted to engage the ears of the matrices if they are out of position and carry them downward to their'proper places.

In the drawings 1 have shown my device adapted for application to commercial linot pe-machines, the drawings being limited to t ose arts of the machine with which I am direct y associated.

-Esme i is a perspectiveviewlooking from 1 the rear and showing the front wall of the assembling-elevator and the front wall of the intermediate channel with my switch therein. Fig. 2 is a face view of Fig. 3 is a perspective view 'of the assemblerelevator and intermediate channel looking from the front with portions broken away.

Referring to the drawings, 1 represents the vertically-movable assembling-elevator having the usual channel in the top to receivlthe matrices Z, which are composed or assembled in line therein.

M is the stationary, intermediate channel into and through which the line of matrices is passed horizontally from the assembler T.

It will be observed that each matrix is pro-' vided with an upper character 2 and a lower.

character .2. e assembling-elevator is provided with a lower which the ears of the matrices are sustained when they are to be used at the lower level, so as to brin their up er characters into action. It is a so prov] ed with a secondhorizontal shoulder 11, which may be retracted,

the same parts.

horizontal shoulder t, on

upon which the matrices are seated when to be used at the higher level to the are y The bring their lower characters into action. intermediate channel is horizontal grooves with s oulders m and m to receive and guide the ears of the matrices when assembled in the upper and lower positions, respectively.

rovided with two The parts so far described may be of the;

same construction and arranged to operate in the same manner as the parts indicated by corresponding letters in Patent No. 615,909. My improvement has reference to the means for guiding the ears Iproperly into the lower groove in the event 0 the matrices e-.

ing accidentally lifted above their proper po 7 v sitions on the lower shoulder of the assem-- bler I atthe time of theirbeing transferred.

For this purpose I provide the verticallymovable switch K, such eral figures, consisting of a plate seated in a recess of the side of the channel M and as shown in the sev- TOO mounted on a horizontal pivot 7c, so that the end next to the elevator I may be moved upward and downward toa limited extent. 011 the side face of this plate there is a rib is constituting the switch proper and forming a continuation of .the rib betweenthegrooves m and m When the free-end ofsthis switch lis'inits lower position, as mdicatectm F1 g. .1

the ears of the ,matrices being transferred pass over it into the upper groove m. When Y I the elevator is raised to its uppermost position, the end of'shoulder or blade i will act beneath the end of the switch and lift the same to the position shown in Fig. 2, so that if the matrices being transferred rise above the lower supporting-shoulder in the elevator their cars will underride the switch, which will act to draw or force them down so that the cars will pass properly into the lower groove m. It will be observed that the end of the blade i is extended somewhat beyond the side of the assembling-elevator I into the intermediate channel M, as shown in Figs. 1 and 3, so that those matr' -ears which ride beneath the blade are held down thereby un til they have left the assembling-elevator and entered the intermediate channel.

The'spring L is extended from the switch to' the main frame and serves to hold the switch in the lower position except when supported by the elevator I. When the shoulder or blade 2' is advanced. to its inner operative position, so as to sustain matrices at the upper level, it will act beneath the switch as i the assembler completes its upward movement and raise the switch to a horizontalposition,'so that matrices in the upper position may pass over the switch into the upper groove and matricesin the lower position may pass under the switch into the lower groove. It will be understood that when the shoulder or blade i is in its inner position it will overlie the ears of the matrices in the lower position and prevent them from being thrown upward out of place. The switch is of value mainly when the blade 71 is retract.

ed, so that it does matrices. 1

The only essentialv requirement of the mechanism for my purpose is that the switch or guiding device shall override the ears of the matrices and draw them down or hold them down in their lower position so that they may be advanced properly through the lower guide or groove in the in termediate channe It will be manifest to the skilled mechanic that the device may be widely varied in form and arrangement without passing beyond the scope of my invention.

- Having described my invention, what I claim is 1. In a linotype-machine containing twoletter matrices, a switch beyond the assemblingelevator to control theel'evation of the matrices as they are delivered laterally from said elevator.

2. In a linotype-machine, and in combination with the assembling-elevator I, and the intermediate channel M provided with two grooves, a moyahle switch to control the course of the matrix-ears into one groove or the other.

notserve to hold down the device located in the path of the matrix-line 1 .and adjustable to hold the matrices at a low level or permit their passage at a high level.

5. In a linotype-machine, a switch to control the course of the matrix-line, arranged to be actuated by the assembling-elevator.

6. In a'linotype-machine, the combination of the assembling-elevator, the intermediate channel and vertically-movable automatic device to hold down the matrices advancing froirli the assembler to the channel at a low leve 7. In a linotype-machine, an assemblingelevator provided with means for maintaining the matrices of a composed line at a high or a low level as required, a channel through which the matrix-lines are horizontally delivered from the assembling-elevator, and an. adjustable device in said channel to maintain the level of the matrices as they are transferred.

8. A linotype-machine having a grooved guiding-rail,- and a preliminary guide-block adjustable to direct the course of the'matrices during their passage toward the body of the guide-rail.

9. A linotype-machine having a guide-rail, and a preliminary guide-block adjustable with respect to the rail and serving to govern the course of the matrices from the assem-- bler to said rail. j

10. A linotype-machine having a guide rail provided with a lower rib, the upper and lower faces of which are arranged to engage with the matrices of a two-letter machine either in normal or raised position, and ajpre liminary guide-block for directing the matrix lugs to positions above or below said rib.

.11. In a linotype-machine, a guide-rail having a rib arranged to engage with the lower -ugs of normal or raised matrices, and a preliminary guide-block adjustable to direct all of the lugs beneath the rib during ordinary work, and to direct normal and raised matrices below and above said rib respectively, when different faces are used in the same line.

12. In a linotype machine, the adjustable matrix-guide extending beyond the assembler into the intermediate channel.

In testimony whereof I hereunto set my hand, this 18th day of October, 1905, in the presence of two attestin witnesses.
